Slow performance of CalculateFormula with Aspose.Cells for .NET in C#

#1

I am using your Aspose.Cells component in one of my software projects, and am finding the Workbook.CalculateFormula method to be very, very slow with my files. I have created a test console app that simply opens the file using:

Aspose.Cells.Workbook workbook = new Aspose.Cells.Workbook(@"C:\WebTemplate2.xlsx");
workbook.CalculateFormula();

The call to new Aspose.Cells.Workbook takes about 3 seconds, but the call to CalculateFormula takes almost 14 seconds! I am wondering if there is an issue with my file that I can correct that will speed this up, or if there is something in the component that is causing this, or some combination of the two.

I have attached a sample file that I am using to run these benchmarks tests. Please let me know if you see anything that is causing this to be so painfully slow. This is for a web application so 14 seconds will make Aspose.Cells completely unviable as an option for us. Thanks!

Hi,

I was able to reproduce the problem with the xlsx file provide by you with the latest version, however, it now throws exception.

This issue has been logged as CELLSNET-29451.

Please download the latest version: Aspose.Cells for .NET (Latest Version)


C#


string path = @“F:\Shak-Data-RW\Downloads\WebTemplate2.xlsx”;

Workbook workbook = new Workbook(path);

workbook.CalculateFormula();

I downloaded version 6.0.1.2 and was able to reproduce the exceptions. I have modified the file and the exceptions no longer occur. Turns out I needed to add some text at or below the lines the SUMIF function was looking for. If there’s no data below that, it errors. However, CalculateFormula( ) is still taking 14 seconds to complete. I have attached the modified file for you to test with. Thanks.

By the way, thanks for your quick reply, your customer service is great!
